KEEN develops investment views based on long term fundamentals in specific areas of information and communication technology. This enables us to pro-actively approach great entrepreneurs and engage with fore-and-insight. Please see our ideas below for more information.

KEEN will back the best teams in European and North American innovation clusters with a particular focus on cross-atlantic market-entry opportunities. We welcome the chance to engage with European and North American companies that have the ambition to cross the Atlantic.

KEEN will add value to the companies it backs by providing access to an exceptional network of talent and experience. We support you from day one if we are convinced about your company. Human capital first, is a simple but compelling philosophy that permeates our culture, strategy and approach to investing.


In an ‘Always-on’ world, consumers expect access to intuitive and intelligent services, anytime anywhere. Fueled by the ubiquity of connectivity, the proliferation of devices, cheaper storage capacity and computing power; intelligent agents, smart machines, and the broader category of the ‘internet of things’ will gradually go from niche to broad adoption. KEEN believes that the combinatorial effects of these technological forces will unleash a wave of innovation and value creation. No longer the domain of science fiction, the world is transitioning to omnipresent intelligence build around the end-user, not the device or network. KEEN targets companies that enable access to the accumulation of global content, intelligence and services in a frictionless manner.

Categories we are interested in include: Next generation networks | Virtualization | IoT Platforms | Big Data | Machine Learning | Smart hardware | Robotics.

Servicing software in an enterprise versus consumers, or professional versus hobbyist fashion is rapidly becoming outdated. Professional users want consumer grade simplicity and intuitive design, while consumers want the power of sophisticated technology. No longer disparate, demand is increasingly trending towards the middle of what we call the prosumer continuum. KEEN will seek platform and web-services companies leveraging cloud, mobility, open architectures and communities, servicing smart tools to users applicable both in a personal and professional context.

Categories we are interested in include: Education Technology | Platform as a Service | Productivity and collaboration tools | File Management | Analytics.

The material and digital world increasingly mix with seamless handovers between online and offline experiences. Technology has widened circles of trust and diminished transaction cost. As a result consumer culture is fast changing. Consumers and businesses are transacting on a peer-to-peer basis, increasingly sharing and monetizing assets. Companies are unbundling traditional categories by disinter-mediating existing economic models with the help of technology. In this world of convenient transacting, security and identity authentication will become an ever more important prerequisite of consumption. KEEN seeks technology driven companies that bridge the gap of transacting in the material and digital word, as well as companies that can support the foundations of these new models.

Categories we are interested in include: Web and mobile market places | Payment Services | Fin-tech platforms | Digital security | Identity solutions.

Not in our Scope

We will typically not invest in the following technology sectors and categories : Online retail | Digital media | Games | Life sciences | Clean Tech | Gambling

In addition we do not invest in proof of concept phases and KEEN will look for commercial momentum. We like to back companies who are ready to scale internationally.
